WILLTAM RICHARD ANTHONY, OF MEMPHIS, TENNESSEE.

MACHINE FOR TRUING FACEI) WHEELS OR PULLEYS.

Application filed September 22, 1913.

To all whom it may concern.

Be it known that I, WILLIAM RICHARD ANTHONY, residing in Memphis, in the county of Shelby, State of Tennessee, have invented certain new and useful Improvements in a Means for Truing Faced Wheels or Pulleys.

The object of this invention is to provide a simple and efiicient means for scraping off, at a high rate ofspeed, the objectionable elevations in such untrue surface, leaving the face in exact conformity to required specifications, without undue friction in the operation or without unnecessary consumption of power or time, thus combining increased efficiency with reduction in cost.

The distinctive construction and the means employed may be well understood by referring to the accompanying three sheets of drawing in which similar reference numerals indicate corresponding. parts.

Fig. 9 is a view in elevation of one of the supporting brackets with the ring clamps removed; Fig. 10 is a central vertical. section upon lines 7) 7) of Fig. 9; and Fig. 11 is an end elevation of one of the scraping tools.

The special adaptability of my invention to the rim faces of the wheels of band saw mills, as herein illustrated, is due to the fact that these wheels wear and require to be accurately refaced very frequently, and to the fact that in the construction of this machine,

special economy is attained in its facility Specification of Letters Patent.

for attaching, in the amplitude of its adjustments, in the rigidity of its compactness, and in the time and power required in the act of scraping the wheel faces true to requirements.

This machine may be attached to vertical timbers (4) properly placed with reference to the peculiar design of the'band mill so that it may be moved up to the top wheel (1) or down to the bottom wheel ('2) with very little preparation. Or where this arrangement is impossible the machine may just as easily be attached to oblique or horizontal timbers, or even to one vertical and the other horizontal or oblique, as may be easily understood from the accompanying description. In any case the timbers must be rigidly braced, see 5 Fig. 1, to prevent vibration.

As shown in Figs. 1 and 2, the machine is attached to the supporting timbers (4) by bolts (15) passing through'holes in the ends of the containing plates (7) whichsupports the yoke (6) by means of the studs (9) passing through the slots (8), see Fig. 10, and tightened in position by the nuts (13), the studs (9) being threaded into each end of the yoke (6) and locked from farther turning therein by the nuts (12). The hanger yoke (6) is vertically adjustable upon the containing plate (7), after loosening the nuts (13) ,by means of the adjustment screws (14), the studs (9) passing freely through the elongated slots The end supports of the machine frame being in the form of rings (17) are revoluble to any position within the circle, and are clamped in the desired position by the ring clamps (10) at each end which are tightened by the two nuts (11) upon each stud (9). Besides tightenin these ring clamps (10) upon therings (1?), these nuts (11) afford ample lateral adjustment so that by means of this lateral adjustment and the vertical adjustment effected by the screws (14) the body of the machine may easily be alined to the desired position without undue care and unnecessary time spent in setting the supporting timbers, see Fig. 2. The main frame of the machine which has these end ring supports (17) comprises two parallel bars of finished steel, or other suitable material, which bars are preferably rectangular or square, and are placed alike so that one corner of each approaches that of for additional strength the screws (20) tighten in a direction at right angle from v by the pin the bolts (19), see Fig. 3. These parallel bars (16) form the slides upon which the carriage base (30) travels by means of. the longitudinal feed screw (21) which is journaled at (22) inside each end ring and provided with adjustable end thrust nuts and jam nuts (23), being turned by the handle crank (25) which slips over either end of the feed screw engaging the end slot (24) (26) which crosses thecylindrical opening in the handle, see Fig. 6. This longitudinal feed screw (21) is connected .with the carriage base (30) by means of the nut (33) secured to the carriage base (30) by the screws (34), see Fig. 4, and this carriage base (30) being properly fitted upon the slide bars (16) is also provided with the gib plates (31) secured to the carriage base by means of the screws (32) so as to take up all lost motion between the carriage base and the slide bars. Upon this carriage base (30) is mounted the cross feed carriage (27), see Figs. 5 and 6,which is suitably fitted to slide thereon with gib (28) and gib ta-keup screws (29) to prevent lost motion between the carriage and its base.

This cross feed carriage is, caused to slide in its path by means of the cross feed screw ('35) being turned by a handle (36) and threaded into theunder side of the carriage (27). Upon this carriage'is held one or more scraping'tool, or tools, (41) firmly clamped in position by the plate (44) and the bolts (45), or other suitable means, see Figs. 6 and 7. These scraping tools (41) may be used singlyor in series with one corner of one end of each presented to the work see Figs. 2 and 6, or they may be so used as to present one corner of one side to do the scraping, as shown in Fig. 7. These scraping tools may be composed of any hard substance capable of withstanding the heat, but preferably an artificial stone or composition of very hard crystals united by a suitable bond so as to present a very hard and tough outer surface (42) with a more porous and softer interior (43), as represented in Fig. 11, is herein selected, in order-that the hard corner exposes to the work may perform the work of scraping while the soft interior wears away without producing undue friction. These scraping tools may be turned or used interchangeably for the purpose of equalizing wear. In order to overcome vibration from the work of scraping. this carriage (27) is provided with a projecting lug (39) to which is adjustably fastened a lever (38) by a bolt (40), which lever carries a weight (37), which weight overcomes any possible lost motion that may not be entirely taken up indicatorhand being prevented from traveling too far toward the wheel by a limit stop (51), and the point of, this indicator hand (47) is caused to traverse the graduation marks (52) by the action of the unevenness of the wheels surface upon this hard pontact (49). This indicator hand (47) being proportioned so as. to magnify the defects make them veryeasyto ascertain, and in this way enable the operator to do much closer work.

In the use of thismachine simply bolt the hanger brackets to any suitable fastening,

preferably to a vertical timber as shown in Figs. 1 and 2, so that the scraping tools will come in contact with the face of' the wheel By means-of the ring clamps (10) fasten the machine in a position that will make the top of the scraping tools line away from the center of the band wheel so as to expose only one cutting or scraping corner of the tool, or tools, and not the square end of thetool, to the wheels face. Then aline the machine with the wheel in the desire'd position by means of the vertical adjustment screws (14) at either end and by the lateral adjustments obtainable by the nuts (11) upon the studs (9). Set the weight (37 and lever (38) in a position that will hold the carriage firmly in the direction the wheel turns. riage as herein explained and run the wheel very slowly to ascertain whether or not it is round, and move the carriage across the wheels face by the longitudinal feed screw turned by the crank (25) and the tester hand will indicate all the ridges and valleys to be worked out. Then the tester may be removed and the scraping tools inserted, preferably three at once with their end corners exposed to the wheels face until the work of truing is nearly completed then insert only one tool in the same position, and finally for finish'insert one tool crosswise as shown in Fig. 7 The tester may then be again used to verify the accuracy of the finish. Band wheels thus trued should make Place the tester onthe cari lit rim speed of about one thousand to fifteen hundred feet per minute, the lower wheel being driven byits belt and the upper one by the saw (3), the tooth edge being boxed in for safety.

Having thus fully described my invention and its practical application, what I claim as original and desire to protect by Letters Patent is,
